To all whom z'may concern.'

, Be it known that I, WALTER H. SMITH, of Niles, in the county ofTrumbull and State of Ohio, have invented certain new and use- V 5 fulImprovements in Printing-Presses; andv I do hereby declare the followingto be a full, clear, and exact description of the 1n- 4vention, suchaswill enable Others skllled inthe art to whichit appertains to.. makeand use the same. The primary Object of this invention 1s to provide inaperfecting printing press 'havmg se arate printing couples, means forsuccessively throwing olf the impression of the print-ing couples andautomatically stopping the operation of the machine after the impressionof vthe last couple has been T e resent invention is especially designedior machines for printing, or numbering andprintin'g, in one or morecolors,

A on both sides Of a sheet, and embodies two printing couples orcombined printng'and number-lng couples, thestock being autoother.

It is the purpose of my invention not only to throw-off successively theimpression of the separate couples, but to defer stopping the machinewhile stock is in transit therethrough, and to then automaticallyoperate the stop mechanism.

It is s. further object of my invention to automatically restore theimpression of the 85 second printing couple when the impression of thefirst couple is unt-ripped. And a further object is to enable aperfecting press to print stock on one side only and yet be capable ofautomatically. tripping the impression and stop mechanism in the eventof any interruption in the feed supply.

The invention will be hereinafter fully set forth and particularlypointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of aprintingr press showing my improvements. Fig. 2 is an enlarged side viewof the tripping and stop mechanism. Fig. 3 is a plan view of the partsshown in Fig. 2. Fig. 4 is a fragmentary end view. Fig. 5 is a detail.

Referring to the drawings, 1 designates a form-carrying cylinder and 2an impression cylinder of a printing couple. Coperating 65 withtheimpression cylinder is a third cylmatically conveyed from one coupleto the impression of the first couple in the event of inder 3 which ,maybe a numbering cylinder or a second form-cylinder. The printing may bein different colors, since the cylinders l and 3 have separate inkreservoirs and rolls. The stock may be fed to the cylindersautomatically or by hand. IA have shown at 4 an automatic sheet feed ofthe Harris type, and at 5 conveyer rolls for transferringthe stock tothe cylinders.

-6 designates a form-carrying cylinder, and 7 an impression-cylinder ofa secondprinting couple. Cop'erating with impression cylinder 7 is athird cylinder 8 which may be a numbering cylinder or a'second formcylinder, and these two cylinders, 6 and 8, may have separate reservoirsand ink rolls, as shown. This second couple is shown on a lower planethan the first vcou le, but this is not necessary. Stock a ter passingthrough the first couple is conveyed by any suitablemeans, such as tapes9, to the second couple, and from the latter may be de- ,livered to afolding machine or perforator,

or onto an ordinary la boy, or it maybe passed to and through anotherprinting couple.

In connection with the first couple I employ some suitablestock-controlled trip mechanism for tripping or throwing-olf the anyinterruption in the feed supply. Any suitable means may be employed forthis purpose, that shown at 10 being constructed after the mannercontemplated by Letters Patent No. 925,047, issued to me June 15, 1909.IVhen the trip mechanism is operated, by failure in the feed-supply, itwill disengage a dog 11 and release a spring-impelled shaft. 12 to whichthe eccentric bearings' 13 of impression cylinder 2 are con- 95 nected.'When the impression is tripped the partial turning of shait 1Q. underthe action of its spring.I causes the longitudinal movement of ashifting bar 14 which is shown as occupying an inclined position.

At its lower end this bar has a lug or projection 15 on its underside,and above and to one side of this lug is a roller 1G. The lug 1 5normally rests in a'notch 17 in a 1ongitudinally-movable controlling bar18 and 105 moved in its guide 20, and as roller 16 rides 110 Amachinewhile Stock is in transit between separate couples, I provide' forholdingccinl trolling'ba/r 18 in'itsset or shift position until/the lastsheet or .piece of stock has passed through the final cou le.' For thispurpose bar 18 is providedl with a second notch 23 into which tliehookedend ofl a! lever 24-is forced.` by a spring 25 when such notchisbrought beneath such end.

The controlling bar 18.will remain held by 'j lever 24 until, .accordingto the arrangement shown, the impression of the second couple tripped. A

' `{.lhe impression 4cylinder 7 Aof the second couple is mounted-neccntric bearings 25,

^ which bearings ai'egciinected to a springiinpelled shaftn26 which isnormally' held by a. lev'e 2T which lis 'caused to release saidshaftwhen'trip mechanism, indicated at 28, islactuabed i'ipon failure inthe feed supply. lever 27 1s connected by a link 29 to an ifm SO'oftheftrip mechanism, and when "the latter is actuated by failure in thefeed rejecting end of arm 30 will pp' the ree end of lever 24 to releaseenga br118 lwhich then be impelled, by its spring 19 the machine. Thiswill not occur, however, until the tri -mechanism of the seoond'cou leis actuate bythe nonpresence Aoft stc `If additional couples should beemployed the im ressions will be .40 tripped successively, but t e primemover would not be brought to rest until after the last piece of stockhas assed throughA the final couple. I preferab y provide the finalcouple with means for automatically restoring the impression in eachcycle of operation, and the Asame is shown as comprising a lever 35, aconstantly-operating cam 36, and a projection 37 of shaft 26 with whicha lateral projection 38 of lever" 35 wi ll engage to move said shaft torestore the impression. Unless the feed supply has been renewed,however, the shaft 26 will not be engaged and held by lever 27.

From what has been said it will be seen that notwithstanding thedistance that separates the two printing couples the tripping of thefirst couple 'will not interfere with the continued operation of thesecond couple until the sheet'last through the first couple has passedthrough the second couple, and thereupon the controlling bar of theprimemover will be released to bring the machine to rest.` p

In. order that a press normally intended as a perfecting press may beutilized -for printing on one side only,-I provide strippers 40,A

-stock instead of passing to conveyer 9 will .fall onto lay-boy 41, butwhen the machine is used for printing on both sides the strippers aremoved into the positions shown in full lines. When the machine is usedfor printing on only one side it is necessary to ring it to rest whenthe impression of the first couple is thrown off. To this end I rovidean eccentric 42 to prevent lever 24 rom engaging controlling bar' 18.When bar 14 is actuated by the partial 'rotation of spring-impelledshaft 12, and bar 18 is moved longitudinally, in opposition to itsspring, such bar will immediatelyV fly back,

under the infiuence of its spring, as soon as lug 15 is lifted fromnotch 17, and thereby stop the press.
